[0054] The pressing ring 7 is sleeved at the intersection of the first cross rod 301 and the second cross rod 302, and the pressing ring 7 is located above the hinged shaft 303.

[0055] In specific implementation, as shown in Figure 2 , at this time, the clamping mechanism 3 is in an open state, the pressing ring 7 is in the lowest position, and the part of the first cross rod 301 and the second cross rod 302 above the hinged shaft 303 forms a V-shaped structure, that is, the distance between the first cross rod 301 and the second cross rod 302 gradually increases from bottom to top.

[0056] When clamping is performed, the pressing ring 7 is driven to move upward by the lifting adjusting mechanism, the pressing ring 7 presses the first cross rod 301 and the second cross rod 302, the plate body 304 at the bottom end of the first cross rod 301 and the plate body 304 at the bottom end of the second cross rod 302 are close to each other through the hinged shaft 303, and clamping is performed through the clamping plates 305 on the two plate bodies; during the above clamping process, the top end of the first cross rod 301 and the top end of the second cross rod 302 compress the first spring 307, so that the first spring 307 generates compression deformation.

[0057] When the clamping is released, the pressing ring 7 is driven to move downward, and is restored to the height as shown in Figure 2 , through the compression elastic force of the first spring 307, the first cross rod 301 and the second cross rod 302 are pushed, so that the two clamping plates 305 are loosened.

[0058] As shown in Figures 2-5 , the lifting adjusting mechanism comprises a support frame 6, an elastic telescopic rod 10 and a cable 9, the support frame 6 is fixedly connected with the inner wall of the first end pipe 2, the top end of the support frame 6 is rotationally connected with the hinged shaft 303, the elastic telescopic rod 10 is installed on the support frame 6, and a connecting seat 8 is installed at the top end of the elastic telescopic rod 10, the connecting seat 8 is fixedly connected with the pressing ring 7, and the bottom end of the cable 9 is connected with the connecting seat 8.

[0059] The elastic telescopic rod 10 comprises a fixed sleeve 1001, a movable rod 1002 and a second spring 1003, the bottom end of the fixed sleeve 1001 is fixedly connected with the supporting frame 6, the movable rod 1002 is connected with the fixed sleeve 1001 in a clearance fit, and the top end of the movable rod 1002 is fixedly connected with the bottom surface of the connecting seat 8, the second spring 1003 is arranged in the fixed sleeve 1001, and the fixed sleeve 1001 and the movable rod 1002 are elastically connected through the second spring 1003.

[0061] The lifting adjusting mechanism slides upwards on the second end pipe 5 through the movable sleeve 4, the top frame 401 on the movable sleeve 4 pulls the inhaul cable 9, the inhaul cable 9 pulls the connecting seat 8 to move, the connecting seat 8 drives the extrusion ring 7 to move upwards, and the connecting seat 8 drives the movable rod 1002 on the elastic telescopic rod 10 to move upwards, so that the second spring 1003 is stretched, the above operation realizes the upward adjustment of the extrusion ring 7, and after the adjustment, the positioning is realized by inserting the positioning plug 11 into the positioning groove 501, so that the position of the upward adjustment is kept.

[0062] In the process of making the extrusion ring 7 reset downwards, the positioning between the positioning plug 11 and the positioning groove 501 is released, the movable rod 1002, the connecting seat 8, the inhaul cable 9 and the extrusion ring 7 are reset downwards through the stretching force of the second spring 1003, the inhaul cable 9 pulls the top frame 401 of the movable sleeve 4, and the movable sleeve 4 is reset.

[0065] When the movable sleeve 4 is pulled to move upwards, as shown in Figures 5-6As shown, the positioning groove 501 is a right-angled triangle, and the bottom is a plane. When the movable sleeve 4 moves, the positioning insert block 11 on it moves up together (the end of the positioning insert block 11 close to the positioning groove 501 is inclined and has an inclined surface). The positioning insert block 11 can be separated from the positioning groove 501 through the extrusion of the inclined surface of the positioning insert block 11 and the inclined surface of the positioning groove 501, and the positioning insert block 11 can enter the next positioning groove 501 through the elastic force of the third spring 12, so that the movable sleeve 4 moves up and is not blocked by the positioning insert block 11 and the positioning groove 501; at the same time, after moving up, the positioning insert block 11 is inserted into the positioning groove 501, and the plane at the bottom of the positioning groove 501 blocks the positioning insert block 11, so that the movable sleeve 4 cannot move down.

[0066] When the movable sleeve 4 is reset, the positioning insert block 11 is separated from the positioning groove 501 by pulling the positioning insert block 11, and the separation state is maintained, so that the movable sleeve 4 loses the positioning and can move down to reset.
